I am getting my supermacro (SM) bass adjusted also. I could not tell the difference either with my SuperMacro's Extra Bass Boost feature turned on and off either.
I pre-ordered my SM, it took a month to process and recieve my order,
I berly had a weekend to enjoy the amp, then I mailed my SM this past
Monday for adjustments. We are all in the same boat here. Xin improves upon
his products based on user feedback. So rest assured when you recieve your
order it should contain the latest improvements, as that is what it seems like
is going on IMO.
For those concerned, posted by XIN ...

Xin:[OUOTE]"Upon many requests, I have increased the default bass boost amount. Amps that have serial # equal or greater than 04120101 already have this. If you already received your amp and like to increase the bass boost, you may send it back at anytime for free upgrading."[/QUOTE]

I didn't take notice of the serial number when I recieved my SM, (and it is not listed on the invoice reciept I recieved with my SM anyways) but I guess my SM will be taken care of by Xin. I am a first time buyer also, and turned over my savings for my SM. It is hard to be Patient, but we know that Xin is working hard to deliver and support a quality product.
Definately, If you have concerns about your SuperMacro order, let your voice be heard and post on Xin's Fixup Support Forum. His operation is what it is, and we will eventually be able to enjoy what we paid for. Or sell it, or return it and get your money back.
I suppose there aren't alot of posts from users of the SM because of all of the mentioned above that is currently going on. Once I have my rig finally set up I will post my impressions on the SM.
